Best ResponseYou've already chosen the best response.1partial derivative means u treat other variable as constant. u know this ?

Best ResponseYou've already chosen the best response.1Right, so we treat y as a constant in the first one..

Best ResponseYou've already chosen the best response.1absolutely! that was my next statement, that u need log diff. here.

Best ResponseYou've already chosen the best response.1In my experiences with log diff I always had a function in the form of y = f(x)^g(x).... So what do we do here?

Best ResponseYou've already chosen the best response.1do we write y = ......?

Best ResponseYou've already chosen the best response.1taking log on both sides, u get log y = g(x) log f(x) then use product rule

Best ResponseYou've already chosen the best response.1u'll also need a chain rule for this....

Best ResponseYou've already chosen the best response.1oh dear! the y on left and on right are different, u should have used g or some other letter

Best ResponseYou've already chosen the best response.1oohhhhhh.. that's where I went wrong... this is off my last quiz :/

Best ResponseYou've already chosen the best response.1so it'll be g'/g on the left?

hartnn

Best ResponseYou've already chosen the best response.1yes, after doing product rule , u resubstitute for g

Best ResponseYou've already chosen the best response.1same for 2nd question, just replace x with y and y with x

Best ResponseYou've already chosen the best response.1right... I just messed up on calling the function y... messed with my head.
